ionosphere

Then he seemed to notice for the first time that they were high in the ionosphere.

"But I'll certainly try to solve them before we take off for the ionosphere!"

It would also help if we could be inside the ionosphere."

Not for ships to land by, but to draw power from the ionosphere!

Even now, we do not understand all the processes occurring in the ionosphere.

It is the international standard for the terrestrial ionosphere since 1999.

The rocket was used to conduct research into the ionosphere.

Some of those frequencies will go all around the planet under the ionosphere.

It was completely trapped by the ionosphere, no power getting away from the Earth.

"But in the ionosphere the plasma is much less dense."

But how do you feed the current into the ionosphere?"

No, son, the ionosphere is the ceiling until we think up something better than rockets.

Hence, most experiments on the ionosphere give only small pieces of information.

It's now known that in fact the waves are reflected by the ionosphere.

The effects of the ionosphere generally change slowly, and can be averaged over time.

The wave is confined between the surface of the earth and to the ionosphere.

"Sir, that will take us through the ionosphere and into the atmosphere proper."

Employed radio instruments in order to study the structure of the ionosphere.

This showed the ionosphere had a much more complex structure than first anticipated.

It was hoped to obtain information about communication through the ionosphere.

The comet stuff is playing pure hell with the ionosphere.

Travel down through the interior of the earth then back up into the ionosphere to learn how the magnetic field works.

Its primary mission is to count electrons in the Earth's ionosphere.

The other two experiments will study the Earth's ionosphere.

"A bad disturbance in the ionosphere could bring satellite communications down for several hours, even days."
